"I did not know about the Building Regulations until my local installer gave me advice about it. I do not want my windows replaced yet but I am thinking about it for next year. The FENSA installer was very helpful, taking the time to explain things to me, without making me feel obliged that I should buy from him."

"In this day of people only complaining about this and that, I though I would write to you about one of your staff members. I had to contact your office today regarding a particularly awkward customers of ours which we had made an error on her FENSA certificate, totally our fault, not yours. I spoke to your staff on the FENSA helpline about our mistake and she was able to rectify the problem for us, thus leading me to write you a letter of thanks and gratitude to one of your staff."
